Yes, I test everything on myself. Before I bring a treatment into the office, I want to understand the experience firsthand, what it feels like, what I notice, and whether I believe the results are worth it.

Mom tried to teach me how to massage my face when I was a teen. Of course, I didn’t listen. Instead, I became a dermatologist.

Even dermatologists get hair thinning. When I noticed clumps of hair in the shower drain, I checked the same factors I look for in my patients, including: hormones, thyroid, iron, deficiencies and toxicities.

I’ve injected filler since 1996 and skin boosters since 2018. Every year I travel to Europe and Asia to work with physicians using products and techniques we won't have in the U.S. for years.

When I broke three ribs this Spring, I couldn’t do my usual workouts.

Is Volufiline really filler in a bottle?

I just got an Oura Ring 5 because as a dermatologist, I look beyond the surface for clues about what may be affecting your skin.

Got sunburned? Remember that a sunburn is more than temporary redness.

Have you ever looked in the mirror and thought, “Did my face age overnight?”

U.S. sunscreens are finally getting newer UV filters like Bemotrizinol (Tinosorb S), an ingredient that’s been used safely in Europe and Asia for years.

When should you start Botox? Not by age — by movement.

Getting dressed is different when people trust you with their faces.

After more than two decades caring for patients, one thing is clear: my patients who take the best care of their skin aren’t those with 10-step routines, but those who actually listen to their skin.

Can laser make brown spots darker? Yes, if the diagnosis is wrong.

Long summer days call for more than sunscreen. What you eat plays a role in supporting healthy skin, too.

Vacation is important, but patient care doesn’t stop when I’m away.

The recent passing of an Estée Lauder executive has understandably raised questions about the safety of cosmetic fillers.

My Dad turned 93 and still sprints up stairs.

The patient thought it was dry skin. It wasn’t. The image is a parasite under the microscope. But this Reel is not really about parasites.

I injected GHK-Cu after breaking three ribs. I was in pain and willing to consider anything that might help.

Long before a treatment becomes trendy in the U.S., I’ve usually seen it already in Asia: in clinics, pharmacies, and conversations with dermatology and plastic surgery colleagues.

My first keynote. The night before, I was wrangling PowerPoint slides at 2AM.

SPF makeup counts. With a catch. Tinted moisturizer & makeup with SPF can protect your skin, but only if you use enough.

At 21, these stairs led to my fourth-floor walkup. This week, they led me back to Harvard Medical School to help shape how we train young doctors.

I went to @livelong_media, a women’s health and longevity summit, and came back with three takeways I’m bringing back to my patients:

Not everything new belongs in my office. Before I offer a new device, I study the data, speak with the engineers and scientists who built it, and look closely at safety and reproducibility.

On National Doctors Day, I'm grateful for the doctors who took care of me recently.

First time back in the gym after my ski accident.

If your retinol isn’t doing much, it may be the type, not the product.

Spring Break travel can be rough on your skin. Three things people underestimate:
